IMPROVEMENT IN BoTTLE-sToPPERs.

Specification forming part of Letters Patent No. 197,890, dated December4, 1877 application filed September 24, 1877. l

To all whom it may concern:

Beit known that I, FRANK W. PERRY, of Philadelphia, Pennsylvania, haveinvented a new and useful Improvement in Bottle-Stoppers, of which thefollowing is a specification: My invention relates to an improvement inthat class `of bottle-Stoppers in which a lever adapted to a collar onthe neck of the bottle is caused to depress the stopper on the edge ofthe mouth; and the object of my improvement is to so combine a slottedlever with projections on the collar and stopper that the latter can betightly compressed by a slight exertion on the lever.

In the. accompanying drawing, Figures 1 and 2 are perspective views of abottle with my improved stopper; Fig. 3, a side view; Fig. 4, a planview of the collar, and Fig. 5 a perspective view of the device forsecuring the collar. y

The collar A may be madein two parts, secured together in the mannerdescribed hereinafter, or it may be constructed for attachment to theneck A of the bottle in any of the modes now adopted in connection withbottle-stoppers ofthe class to which my invention relates. In all cases,however, the collar must have opposite projections or trunnions a a',adapted to the slots b of the two arms B B, which are arranged onopposite sides of, and close to, the bottle, and are connected togetherby the yoke d.

H is the stopper, the upper portion of which is made of metal, and thelower portion of rubber, as usual, the metal portion having oppositeprojections e @which are connected by links j to eyes m on the slottedarms B.

In adjusting the stopper to the mouth of the bottle, as shown in Fig. 3,the arms B must be elevated, the lower ends of the slots being incontact, or nearly so, with the projections ofthe collar, so that therubber of the stopper may pass freely over the edge of the mouthpreparatory to being placed on the mouth itself,iafter which the armswill descend to a limited extent. The yoke d is now depressed from aboutthe position shown in Fig. 3 to that seen in the perspective view, Fig.l, when the stopper will be irmly secured to the mouth of the bottle,the pins a resting in the enlarged ends of the slots in the arms B, soas to pre vent accidental movement of the latter.

In thus depressing the yoke d, the latter,

with its arms B, acts as a lever with a constantly-changing fulcrum,for, as the lever is depressed, the arms B slide on the fulcrumprojections a, and the eyes m approach nearer and nearer to the saidfulcrums, until the i11- ner ends of the slots in the arms reach theprojections a., as shown in Fig. 1, whenv the eyes mbear such relationto the said projections that the stopper will be locked firmly to themouth of the bottle, from which it cannot be detached without firstraising the yoke or pushing the arms B in the direction of the arrow,Fig. 1, by doing which the stopper may be released, and afterward thrownback, so as to hang down the neck of the bottle, where it cannot be anyimpediment to the filling ofthe bottle. (See Fig. 2.)

' There is an advantage in-this constantlyincreasing leverage exerted onthe stopper as the yoke is depressed, for as the compression of therubber increases the leverage increases; and hence the desired tightjoint is completed by a comparatively slight eifort, the releasing ofthe stopper being also ett'ected with very little exertion.

The collar A is made in two parts or seg ments, w and fw. These areloosely hooked or permanently hinged together at fr; but the other endsof the segments are,.conne cted together by a Theaded link, J, andcam-lever I, as show-n in Figs. 4 and 5.. The T-head of the link isconnected to the slotted and hooked end y of the segment w, and the stemof the link inserted into the slot of the hooked end y of the segmentw', againstwhich hook bears the cam of the lever I, which is hinged tothe link. Y

By turning this lever from the position shown by dotted lines to thatshown by plain lines in Fig. 4, the segments :are made to tightlyembrace the neck of the bottle, and, after turning the lever in a"contrary direction, the pressure will be removed from the segments, andthe latter may be withdrawn from the neck of the bottle.
